SRAM DualDrive Shifter (27-speed)

SRAM's DualDrive is a unique drivetrain that combines a three-speed internal-gear hub with an external cassette and derailleur. The result is a wide-range of gears in a clean, one handed control system. The DualDrive shifter features a grip shift motion for the rear derailleur and a thumb trigger that controls gear changes in the internal hub.
